So, for a few months now I have been friendly with this guy Adam (not his real name), we see each other two or three times a week as he is the football coach of my ds. We have been flirting a bit lately, he is always looking over in my direction/holding my gaze for longer than normal and the last few weeks he asked to walk together to the train station and when we see/leave each other he kisses me goodbye (3 x on the cheek). He also pulls me in close to him when we are talking and held my hand last week! We talk to each other a lot! He always asks me if I will be attending any of the (many) events outwith normal training. So, I had thought perhaps this mutual attraction might lead somewhere.
About a month ago a woman appeared at training a few times (Penny), but he never introduced her to me despite the fact she was sitting right beside me and he was talking to me! He didn't engage with her at all!
Last week as we were walking/talking he confirmed directly with me that I am no longer with the father of ds (2nd time he has done so), and he told me how long he had been split from his wife. So far, so normal.
Yesterday through a friend of a friend I discover that he got engaged to Penny last month! She has posted the engagement on fb (I know I know Facebook!), pictures of them together etc. He isn't "tagged" in the photos at all, and nor has he commented/liked any of the comments (he uses fb regularly for work its not that he hasn't seen it).
Why didn't he just say last week he is engaged (also, not sure if its entirely relevant but he isn't divorced from his current wife so, engaged?)
Did I just misread the signals? Tbh its possible. Have I just misinterpreted friendliness for something else? I live somewhere where the people aren't known for being overly warm/friendly. I will see him tonight, should I mention it at all?
I appreciate this isn't a huge issue on the relationships board, but its really puzzling me. I also realise I sound 15 or so, we are both mid/late 30's.
